On March 22, 1978, a Long Island, NY waterproofing contractor named Leopold (Leo) Ladenhauf was reported as a missing person by his wife.
Speaking from the family residence, located at 27 Lakeside Avenue in Lake Grove, a quiet residential community on Suffolk County’s north shore, Mrs. June Ladenhauf told police she hadn’t seen or heard from her husband since he left home two days earlier on March 20.
